#5 Bring Water Shoes
A friend suggested this and it was definitely a good idea. The ground surface is hot and slippery. Flip Flops and slides are not as safe as water shoes. Water shoes will stay on your feet when you're on the rides.
#4 Arrive Early
Arriving early is a good idea for any Disney park. The water parks are no exception.
You can grab chairs, lockers and set up before the rides open. We were first in line for Mayday Falls a single person tube ride that later had long lines.
#3 Bring a Towel
The price of a ticket does not include a towel, but you can rent towels at the park for $2. I suggest bringing your own. Of course, if you're traveling light bringing your own towel is not always an option.
#2 Rent a Locker
Large lockers are $15. They're big enough to hold a back pack and your valuables. Some visitors are more trustworthy than I am and left their belongings on chairs. Lock up your phones and let the kids enjoy the park and rides.
#1 Remember Water Safety
Read the signs, obey the rules and keep an eye on your kids.
